摘要： In a pattern processing apparatus, a registration data preparation unit performs two-dimensional discrete Fourier transform of image data of a registration pattern to prepare registration Fourier image data. A collation data preparation unit performs two-dimensional discrete Fourier transform of image data of a collation pattern to prepare collation Fourier image data. A data synthesizing unit synthesizes the registration Fourier image data with the collation Fourier image data, both of which consist of phase and amplitude information, to output first synthesized Fourier image data. An image processing unit performs Fourier transform of the first synthesized Fourier image data to output second synthesized Fourier image data representing intensities of correlation components. A pattern collation unit collates the registration pattern with the collation pattern on the basis of the intensities of the correlation components of pixels in a correlation component area set in the second synthesized Fourier image data. An amplitude suppressing processing unit performs amplitude suppressing processing of one of the registration/collation Fourier image data and the first synthesized Fourier image data to extract only the phase information.

摘要： A plurality of images (I, J) of an object (M) when viewed from different viewpoints are taken in. One of the images is set as a standard image (I), and the other image is set as a reference image (J). One-dimensional pixel data strings with a predetermined width (W) are cut out from the standard image (I) and the reference image (J) along epipolar lines (EP1, EP2) calculated from a camera parameter (CPR) and the reference point (p). Calculating a phase-only correlation function from the cut one-dimensional pixel data strings will obtain a correlation peak position (Pa1). A positional shift amount (d) from the correlation peak position (Pa1) is obtained. A search is made for a corresponding point (q) corresponding to the reference point (p) based on this position shift amount (d).
